Configuration of MsSqlTabSizeTest

This test auto-discovers the databases with tables that exceed a configured size limit, and reports the count of such ‘large sized tables’ for each database. You can use the detailed diagnosis of the test to know which tables in a database are of a large size.

The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed. 

• Specify the host for which the test is to be configured in the HOST text box.

• Specify the port on which the server is listening in the PORT text box.

• If the MS SQL server being monitored is an SSL-enabled server, then set the SSL flag to Yes. If not, then set the SSL flag to No.

• If a Microsoft SQL Server 7.0/2000 is monitored, then provide the name of a SQL user with the Sysadmin role in this text box. While monitoring a Microsoft SQL Server 2005/2008/2012, provide the name of a SQL user with the CONNECT SQL, VIEW SERVER STATE, VIEW ANY DEFINITION, VIEW ANY DATABASE, and PUBLIC roles in the USER text box.

• Specify the password of the specified USER in the PASSWORD text box.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• In the INSTANCE text box, enter the name of a specific Microsoft SQL instance that is to be monitored. The default value of this parameter is "default". To monitor a Microsoft SQL instance named "CFS", enter this as the value of the INSTANCE parameter.

• By default, none is displayed in the DOMAIN text box. If the ‘SQL server and Windows’ authentication has been enabled for the server being monitored, then the DOMAIN can continue to be none. On the other hand, if ‘Windows only’ authentication has been enabled, then, in the DOMAIN text box, specify the Windows domain in which the managed MS SQL server exists. Also, in such a case, the USER name and PASSWORD that you provide should be that of a user authorized to access the monitored SQL server.

• In some Windows networks, NTLM (NT LAN Manager) may be enabled. NTLM is a suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users. NTLM version 2 (“NTLMv2”) was concocted to address the security issues present in NTLM. By default, the ISNTLMV2 flag is set to No, indicating that NTLMv2 is not enabled by default on the target Microsoft SQL host. Set this flag to Yes if NTLMv2 is enabled on the target host.

• The test will report the count of those tables that are of a size greater than the value (in GB) specified in the TABLE SIZE GB text box.

• If the value chosen against the ISPASSIVE parameter is Yes, then the SQL server under consideration is a passive server in an SQL cluster. No alerts will be generated if the server is not running. Measures will be reported as ‘Not applicable’ by the agent if the server is not up.

• To make diagnosis more efficient and accurate, the eG system embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a specific server, choose the On option against DETAILED DIAGNOSIS. To disable the capability, click on the Off option.

  The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability

  • Both the bad and normal frequencies configured for the detailed diagnosis measures should not be 0.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a "*" beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a "$" or contain a series of "*". A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
